I think all you will need to do here is run the game converter, back up your ff7.exe and data folder. then place the new data and direct folders from the mod in the ff7 directory and overwrite. Then just launch 7th heaven, activate any texture/music/movie mods you want to use then launch. Havent used bootleg in years so im unsure what all the ficedula and bootleg folder files are supposed to do, but i dont see an flevel anywhere in the download so the changes you get are going to be in battle only.

(sega cheif quote)Alright, so start by getting the R02 Reunion mod and running it. Only select the Menu Overhaul (deselect everything else). This'll move all your data folder files + .exe into a back-up folder inside the FF7 folder (get rid of these if you have back-ups already, but maybe keep the .exe if you don't have another copy).

Now you need a Hardcore mod battle.lgp. Grab that and replace the one in your data folder with it. While you're at it, put the Nightmare scene, kernel, and flevel.lgp files in as well (note that you need the full flevel; the 'slim' flevel is more of a placeholder than anything else). You'll also need the Nightmare .exe. Get that stuff from the links on the Qhimm thread.

Now we need to add some files to the char.lgp. Download the Aeris Revival mod and it'll come with some loose char.lgp files. Decompile a char.lgp and stick the new files inside, then recompile it. You'll need ULGP for this.

Last things aren't strictly necessary; the title screens, custom music, etc. Download + place them in the necessary folders if you want them. If you don't put the custom OST in then the wrong music plays in certain places, making for some odd scenes according to the mod author (but I play with no music).﻿
